This 3-inch turbo exhaust pipe is built from mandrel bent 304 thick wall stainless steel for 2011–2015 Chevy and GMC 6.6L LML Duramax diesel engines. A fiberglass based heat wrap is included to provide insulation from the passenger compartment and firewall due to the proximity of the larger, higher flowing pipe. This turbo exhaust pipe replaces restrictive factory downpipe designs to support improved exhaust flow, reduced backpressure, lower EGTs, and enhanced turbo response.
